SPECIFICATION forming part Of Letters Patent No. 62 5,192, dated May 16, 1899.. I

Application filed April 4,1898. Serial No- 676,2 83. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS ELI NORTON, a subject of the Queen of Great Britain, residing at Gosport, in the county of Hants, England, have invented new and useful Improvements in Anchors, of which the following is a specification.

My invention relates to anchors, and comprises the improvements hereinafter set forth.

In the accompanying drawings, Figure 1 is a plan, and Fig. 2 is a side elevation, showing an application of my said improvements to a stockless anchor. Fig. 3 is a plan, and Fig. 4 is a side elevation, 011 a reduced scale, of part of a similar anchor, but with a stock applied thereto.

Like letters indicate corresponding parts throughout the drawings.

a is the shank or stem of the anchor, which may, as shown in Figs. 1 and 2, be provided at each end with a hole or eye to receive a bolt g or h, by which a suitable shackle e or f can besecured to the said shank, the said holes or eyes and shackles being preferably arranged at right angles to one another, as shown in the drawings. According to my invention the shank Ct is provided with a boss, enlargement, or swelling 0%. This boss has an opening a running entirely through it, and it is slotted, as shown at a, at right angles to the opening a. It will be seen that the two opposite sides of the slot a incline to ward each other and the two inclined walls of each side meet at the point Q The opening W is intended to receive suitable flukes b and the slot a. to receive a tripping-piece c. This tripping-piece is made in aform approximating to a double wedge. It is an easy fit within the above-mentioned slot ct and is provided with an opening in line with the one CLXX in the shank a and with two openings to receive bolts (1, one on either side.

The flukes b b are formed separate and preferably with the blades thereof in the form of arrow or spear heads, as shown. Each fluke has a reduced portion 5, adapted to fit into and rotate freely in the opening a while they each terminate in a square or other suitable shaped part or portion b adapted to fit in the correspondingly-shaped opening in the tripping-piece c and secured therein by means of the bolts, screws, pins, keys, or cotters d or their equivalents. The tripping-piece 0 projects on either side of the slot a and is free to turn or move therein until it comes in contact at two points with the inclined sides of the said slot. Thus the flukes b can turn or pivot therewith in either direction to a suitable inclination or angle relatively to the shank ct, and thereby enable the anchor to bite or take the necessary hold upon the ground.

The anchor as described may be used without a stock; but if a stock be employed it can be formed and fixed as shown in Figs. 3 and 4. j represents the stock, which is formed with a central hollow boss 3' of such size that it can be passed over the extremity of the shank a before the shackle fis fixed thereon. An opening j is provided in the bossj and shank a, through which a bolt or its equivalent is passed and whereby the stock is retained in position.

It will be seen that my improved anchor is so constructed that the flukes b can be separately and very readily disconnected from the shank a, thereby greatly facilitating the stowage thereof for storing or transport; also, that a worn, broken, or damaged fluke can be readily removed independently of the other one and a perfect one substituted.

Upon the anchor being dropped in the usual manner it will fall with the shank a upon the bottom and with one of the ends of the trip ping-piece c entering the ground. Immediately the cable attached to the shackle fbecomes taut through the pull ofthe ship the tripping-piece c, and with it the flukes b, will become canted, in the manner clearly shown in Fig. 2. Any further pull of the ship will simply cause the flukes b, owing to their degree of inclination, to become further buried in the ground and maintain a firm hold therein. As, however, the cable is hauled in the shank a will be raised and, the pull becoming more nearly vertical, the ground above the flukes b will be easily broken up and the latter will lose their hold, together with the tripping-piece c.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The combination of the shank having a boss near its lower end provided with a transverse duced portions of the flukes to the tripping- 10 opening, and a slot in line with the axis of piece.
